Solving for the low-rank tensor components of a scattering wave function
Jacob Snoeijer, Wim Vanroose
Atomic and molecular breakup reactions, such as multiple-ionisation, are described by a driven Schrödinger equation. This equation is equivalent to a high-dimensional Helmholtz equ…
Initialization of lattice Boltzmann models with the help of the numerical Chapman-Enskog expansion
Ynte Vanderhoydonc, Wim Vanroose
We extend the applicability of the numerical Chapman-Enskog expansion as a lifting operator for lattice Boltzmann models to map density and momentum to distribution functions. In e…
Exploration of stable and unstable vortex patterns in a superconductor under a magnetic disc
N. Schlömer, M. V. Miloševıć, Bart Partoens +1
The stable and unstable solutions of a square 2D extreme type-II superconductor are studied in the field of a magnetic disc. We use a preconditioned Newton-Krylov solver to find th…
Efficient determination of the energy landscape of nonlinear Schrödinger-type equations
Nico Schlömer, Daniele Avitabile, Milorad V. Milošević +2
We describe a systematic approach for the efficient numerical solution of nonlinear Schrödinger-type partial differential equations of the form , with an energy…
Numerical Continuation of Bound and Resonant States of the Two Channel Schrödinger Equation
Przemysław Kłosiewicz, Wim Vanroose, Jan Broeckhove
Resonant solutions of the quantum Schrödinger equation occur at complex energies where the S-matrix becomes singular. Knowledge of such resonances is important in the study of the…
Numerical Continuation of resonances and bound states in coupled channel Schrödinger equations
Przemysław Kłosiewicz, Jan Broeckhove, Wim Vanroose
In this contribution, we introduce numerical continuation methods and bifurcation theory, techniques which find their roots in the study of dynamical systems, to the problem of tra…
Coarse-grained analysis of a lattice Boltzmann model for planar streamer fronts
Wim Vanroose, Giovanni Samaey, Pieter Van Leemput
We study the traveling wave solutions of a lattice Boltzmann model for the planar streamer fronts that appear in the transport of electrons through a gas in a strong electrical fie…
Interference of resonances and the double-pole of the S-matrix in a double well system
Wim Vanroose
We discuss the interaction between two resonant states in a quantum double-well structure. The behaviour of the resonant states depends on the coupling between the wells, i.e. the…
